- A: The insect you showed me is a Millipede, which actually is not a bug or insect at all. Insects have 3 body parts and only 6 legs. Millipedes are commonly known as thousand leggers and belong to a group of arthropods called Diplopods. Millipedes are worm-like, cylindrical animals with many body segments.

Worms A Worm is an elongated soft-bodied invertebrate animal. The best-known is the earthworm, a member of phylum Annelida, however, there are hundreds of thousands of different species that live in a wide variety of habitats other than soil. Most worms live in our gardens and in other soiled areas such as fields and farms. Worms do not have arms, legs or bones, instead, they have a soft, often segmented body which is covered a tiny hairs or bristles that help them move along. Worms breathe through their skin and so it must be kept moist all the time to enable them to absorb the oxygen from the air.

What the Heck is a Hellgrammite? Photo 1: Hellgrammite, the larva of a dobsonfly. Some residents have been recently encountering a large (and to some people a scary) insect larva. This dark colored insect, a hellgrammite (Corydalus cornutus), has an elongate and somewhat flattened body. It has six conspicuous legs as well as a series of filaments on the sides of its abdomen with small finger-like gills clustered at the base. A hellgrammite also has very prominent, strong mandibles (jaws).

Arachnid Most adult mites have four pairs of legs, like other arachnids, but some have fewer. For example, gall mites like Phyllocoptes variabilis (superfamily Eriophyioidea) have a wormlike body with only two pairs of legs; some parasitic mites have only one or three pairs of legs in the adult stage.

segmented worms Annelida. The animals in the Annelida are segmented worms. They have no legs, and no hard skeleton. Unlike mollusks, annelid bodies are divided into many little segments, like rings joined together. There are many other kinds of worms, but only annelids are segmented this way.There are three main groups of annelids, the earthworms (and their relatives), the leeches, and a big group that lives in the ocean and are called polychaetes (pol-ee-keets).here are many other kinds of worms, but only annelids are segmented this way.

13 Things You Didn't Know About Planarians Many species of these worms can regrow their body parts, including a new head, upon decapitation, and are therefore one of the organisms of choice in regeneration research. But they're also being “rediscovered” in several other research areas, including pharmacology and the neurosciences. And they're also pretty cute.

Anatomy The thorax consists of three segments called the prothorax, mesothorax, and metathorax. Each segment has a pair of short legs. A mealworm doesn’t walk very well, but its legs and claws are perfectly suited for burrowing.he thorax consists of three segments called the prothorax, mesothorax, and metathorax.

- Worm Classification. Worms are in a very broad category that is not officially classified in any scientific sense. While most worms are limbless invertebrates, some worms are actually reptiles or amphibians. Many other animals called worms are simply insect larvae that have yet to metamorphose into their adult stage.

- The mouth is at the tapering front end, which is usually slightly darker than the rest of the body; the tail end tends to be more flattened than the head and lighter in color. Its reddish tinge is due to the oxygen-carrying pigment hemoglobin in the blood. The earthworm's body is made up of segments. On each segment, except the first and last, are four pairs of tiny bristles called setae that help the worm move through the earth. It also has five pairs of hearts in the front of its body. The hearts help circulate the worm's blood.

Difference between Caecilians (Gymnophiona) and a worm, legless lizard or blind snake? Answers. Best Answer: Not a worm (annelid) because worms have segmented bodies and Caecilians do not. Worms also do not have a backbone and amphibians (being chordates) do. Not a legless lizard or blind snake (Chordates) because there are species of caecilians that do not have lungs.All lizards and snakes have lungs.Species of caecilians that don't have lungs are able to breathe primarily through their skin, much like we see in many salamander and frog species.ot a legless lizard or blind snake (Chordates) because there are species of caecilians that do not have lungs.

- Best Answer: The earthworm has a cerebral ganglion, which serves as its brain. It is connected to the rest of the body by means of a ventral nerve cord.There is a swelling, called a ganglion, in each segment.. These two cerebral ganglia are connected to the rest of the body as follows: Sensory nerves leave the brain and run forward into the prostomium (extreme anterior end) and first segment. From there, a ventral nerve cord connects all the segments of the worm. 3.

Arachnid The larvae of mites and Ricinulei have only six legs; a fourth pair usually appears when they moult into nymphs. However, mites are variable: as well as eight, there are adult mites with six or even four legs. Arachnids are further distinguished from insects by the fact they do not have antennae or wings. Their body is organized into two tagmata, called the prosoma, or cephalothorax, and the opisthosoma, or abdomen.

Centipedes, Millipedes and Sow Bugs Millipedes (“thousand legs”) are dark creatures that have the appearance of a worm, usually about an inch to an inch and a half in length. Their body is more cyllindrical, unlike centipedes, who have flattened bodies. Millipedes have many more legs than the centipede, sometimes up to 400.

Annelida - Segmented Worms The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body. Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.here are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli.
